Fire hydrants are usually colour-coded so firefighters can tell at a glance the water capacity and pressure available.
Intended as a critical time-saving indicator during a fire, the meaning of the colour codes are not universally standardised though.
The pillar hydrants I see here in Tanjung Malim are mostly red, with a few in yellow.
Behind the hydrant is the Church of the Most Holy Redeemer in Rest House Road. The Catholic church started as a small chapel in 1960 and was rebuilt in 2007.
